NOTE: Of the some 29,000 downloads from 117 countries and over 1,500 institutions that have been made from my BePress Selected Works site, the white paper titled "Basic R matrix Operations" has had over 4,300 downloads from 95 countries. It is the most downloaded. I am very pleased that this paper has been helpful to so many of my statistical colleagues and readers. It's near the bottom of the selections below, so I am giving you the direct URL for it (see below). Log Negative Binomial Regression as a GLM (which I wrote in 1993 to mathematically demonstrate that the negative binomial is a member of the GLM family), Negative Binomial Regression Extensions and Beta Binomial Regression papers have each been downloaded over 2000 times.

ERRATA -- always make sure to check the Errata and Comments/Additions document for all stat books, including mine. Both of my recent books, Modeling Count Data (2014) and Practical Guide to Logistic Regression (2015) now have new e-books with (most) errata corrected. Unfortunately the printed versions still have the errata. For the next printings of each book, errata-fixed versions will be available. Book-sellers may still sell older copies until they run out of stock. Also, readers of "Practical Guide..." will likely appreciate the "Addition to PGLR Chapter 6". It provides a number of Bayesian logistic and beta binomial models using Stata.
